Same xib for iPhone4 and iPhone5 possible?

Question

Is there any way I can design my classes for both iPhone4 and iPhone5 using the same xib?

Answer 1

If you want to make some small changes(e.g images position and sizes, scroll view content insets..), you can use codes to differentiate between iPhone 5 and iPhone 4/4s, and implement your codes inside the if/else statement.

Use this:

to detect the iPhone type.

Answer 2

Well short answer to you question is YES;

Long is :- If you user XCode 4.5 and build app that is universal the NIB files and Classes would work perfectly for Iphone 4 and Iphone 5; Understand for you it important to know the version of SDK of these mobiles not the mobile version them self.

Another thing is that iphone 5 size is little bigger then iphone 4 so you need to design accordingly.. please read my answer at Iphone 5 screen resolution issue for better understanding.

Also look at the How to develop or migrate apps for iPhone 5 screen resolution? answer for more clarification on universal app desing.

Answer 3

Please define below line and check condition based on device.

#define IS_IPHONE_5 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )

if (IS_IPHONE_5) {

        btnBookmark.frame=CGRectMake(0, 460, 100, 70);
        btnBookmark.frame=CGRectMake(150, 460, 100, 70);


    }else{
        btnBookmark.frame=CGRectMake(0, 360, 100, 70);
        btnBookmark.frame=CGRectMake(150, 360, 100, 70);


    }

Answer 4

You can use auto layout feature provided by apple. Please refer to apple document for this:- https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/Introduction/Introduction.html

Answer 5

Use AutoAutoresizing so that u can make app compatible with both iOS 5 and iOS 6. This is easy if your layout is having minimum dependancies. And this is possible for fixing issues with components like UIToolBar. Buttons in iPhone 5.

Answer 6

Yes, you can use the same XIB to design for iPhone 4 and iPhone 5 by using Auto-Layout.

Build an app using iOS 6 as the Base SDK and use the Auto Layout feature to make screens that can scale for all type of screens. You'll need Xcode 4.5 to do this.
